- Position the batt and staple through the back surface of the extended flange to the side of the joist.
- Swing the batt into the cavity, fold the opposite flange over the other side of the next joist, and staple the flange to it spacing staples approximately every 8" (200mm) with beginning and ending staples about 1" (25mm) from the end of the flange. This installation allows full thickness recovery of R-19 insulation in 2x4 construction.
- For R-30 insulation in 2x6 construction, the insulation is compressed to approximately 81/2" (216mm), which results in an installed R-Value of 28 (RSI, 4.93).
- In each case, the insulation should hang approximately 3" (75mm) below the bottoms of the joists.
These installation recommendations are general in nature. Other methods are acceptable. Please consult local building codes for recommendations best suited to the application.
